Griffons are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Griffons will get any or all of these diseases, but it's important to be aware of them if you're considering this breed.

If you're buying a puppy, find a good breeder who will show you health clearances for both your puppy's parents. Health clearances prove that a dog has been tested for and cleared of a particular condition. In Griffons, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand's disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).

• Hip Dysplasia: This is a heritable condition in which the thighbone doesn't fit snugly into the hip joint. Some dogs show pain and lameness on one or both rear legs, but you may not notice any signs of discomfort in a dog with hip dysplasia. As the dog ages, arthritis can develop. X-ray screening for hip dysplasia is done by the Orthopedic Foundation for Animals or the University of Pennsylvania Hip Improvement Program. Dogs with hip dysplasia should not be bred. If you're buying a puppy, ask the breeder for proof that the parents have been tested for hip dysplasia and are free of problems. Hip dysplasia is hereditary, but it can also be triggered by environmental factors, such as rapid growth from a high-calorie diet or injuries incurred from jumping or falling on slick floors. Veterinary care includes giving your Griffon supplements and medicines to help prevent or lessen the pain of arthritis and, in severe cases, surgery.
• Patella Luxation: Also known as "slipped stifles," this is a common problem in small dogs. It is caused when the patella, which has three parts--the femur (thigh bone), patella (knee cap), and tibia (calf)--is not properly lined up. This causes lameness in the leg or an abnormal gait, sort of like a skip or a hop. It is a condition that is present at birth although the actual misalignment or luxation does not always occur until much later. The rubbing caused by patellar luxation can lead to arthritis, a degenerative joint disease. There are four grades of patellar luxation, ranging from grade I, an occasional luxation causing temporary lameness in the joint, to grade IV, in which the turning of the tibia is severe and the patella cannot be realigned manually. This gives the dog a bowlegged appearance. Severe grades of patellar luxation may require surgical repair.
• Eye Problems: The Brussels Griffon's prominent eyes are prone to being scratched and becoming irritated. Be sure to check with your vet if your dog's eyes are red or he is rubbing them excessively.
• Skin Allergies: Brussels Griffons can be prone to allergies. If yours is itching or licking at his paws excessively, have him checked by your vet.
